I have a new 8900 running the new OS .206 and new (2 week old ) sim card. The problem is that my signal is weak and sometimes hits the SOS. I've been with AT&T for several years and have had numerouse phones and have never had this bad of signal. As I type this I have 3 phones here I'm looking at ( Motorolar RazrV3, LG Shine cu720 and my 8900) and both the other phones have 4 bars where the 8900 has 1-2. It hits the "SOS" daily. I have NEVER seen the SOS on any of the other phones? I did google this and it seems to be a problem with the 8900? I have "quickpull" installed and it runs daily so a battery pull woud'nt help? Anyone other than me have worse signal with their 8900 than their other phones? Any fixes or suggestions? Thanks.............
